Document Summary
Genome transmission: different parts of the genome have alternative modes of transmission (comes from only one parent ex. mitochondria maternally inherited) Groups are composed of females and juveniles. Can males recognize their sisters, and mothers when they reassociate with females. Problem: male elephants can keep reproducing for a long time because of their long lifespan. So they can also encounter their own daughters :o. Prediction 1: elephants have evolved inbreeding avoidance because inbreeding depression is severe: inbreeding depression loss of fitness because the consequence of mating with relatives are so severe. So if your chances of mating is 0% then take the risk and mate with relatives because the alternative is not mating at all) Experiment: use genetic markers because can"t do experiments with elephants (their life span is too long). Observe elephant behaviour and watch who mates with who and try to assess whether they"re mating with their own relatives.
